SAMUEL OOLAI-IAN, OF CLEVELAND, OHIO.

IMPROVEMENT IN HAY-PRESSES.

Specification forming part of Letters Patent No. 341.622,Llated March ll, ISGQ.

To all whom, t 71mg/ concern.-

Be it known that I, `SAMUEL CoLAHnN, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful Improvements in Hay-Presses; and Idohereby declare that the following is a full and complete description of the construction and operation of the same,referenee being had to the accompanying drawings, making part of this specification, in which- Figure l is a front View. Fig. 2 is an end view. Fig. 3 is a vertical section vin the direction of the lines X X in Figs. 2 and 5. Fig. 4 is a top View, and Fig. 5 is a view of the under side.

Like letters refer to like parts in the several views. y

The nature of my improvement relates yto the general arrangement of the parts composing the machine, to the mechanical devices for obtaining thepower, and the use thereof in pressing hay, cotton, hemp, wool, iiax, and other similar substances.

In the accompanying drawings, `A A' A2 represent the frame-work of the machine, consisting of rectangular frames made of timber about three by four inches diameter, and halved and bolted together or otherwise secured at the corners. One of these frames, A, is placed at ythe bottom; one, A', at the middle, and A2 at the top. Three sides are lined with plank running up and down, and the front or fourth side is lined but half-way up, as seen in Fig. l, or to the top of the middle frame, A. The interior of the press has the capacity for holding asuflieient quantity of hay or other material for one bale. The front frame, A', to the top is occupied by a door, B, the hinges of which are at the bottom of the door, as seen at B', and are secured by screws to the piece A', as shown in Fig. 1. Both the door and the opposite portion of the back part of the press are pierced with vertical slits C, for the purpose of introducing the binding cords around the pressed bale. The upper piece, D, of the door B is mortised at each end, as at E, Fig. l, and there being tenons upon the corresponding ends ofthe pieces A2. When the door is closed, the tenons enter the mortises at E, and are secured by a pin, a, as shown in Figs. l, 2, and 4. rIhe top F is made strong by timbers F' F2, and the lining is secured crosswise, and provided with transverse slits O' O' O' for the introduction of the bindingcords, which slits agree in position with those previously named, and shown at O in Figs. 1 and 3. The cover is hinged to the piece oi' timber A2, as seen at G G in Fig. 4. `When the cover is opened,it rests against the standard H, which rises at the back part of the machine for that purpose. This standard has a pulley in the top, over which a cord passes to raise the cover, in order to remove the pressed bale. Upon the front edge of the cover are iron hooks I I, Fig. l, which embrace thc outside or the timber D, where they are secured by the pins e c. which penetrate the timber D through the holes c' e', thus giving additional security to the front door, and preventing the cover from rising while in the act of pressing. The bottom K is made in a manner similar to the eover,With slits O2 O2 O2 running transversely and agreeing in position with those shown at C C'. The lengthl and breadth of the bottom is such that it will slide' up and down with ease inside of the body of the press. At about a quarter of the distance from each corner of the timbers of the bottom are placed friction-wheels L L', there being four in all. A chain or rope, M, is secured to the inside oi' thepress about midway of the upper half, as seen at N, Fig. 8, at opposite sides obliquely from each other. Each of these ascends in a easement, M', Fig.' 3, passes under the wheel Ly along the bottom K to the wheel L', up another easement, h' 2,\ Fig. 3,V

over the sheave O,.Figs. 2 and 3, thence to the windass I), which is placed horizontally about midway of the lower half of the press, and provided 'with spiral grooves in which the chain or rope winds. On the outer end of each of these windlasses I) (there being one on each side) is a crank, Q, Fig. 2, by means of which the press is operated in lowering the bottom, and in raising it through the rst quarter of the'distance it rises in the act of pressing.

R R represent levers, there bein-g one attached to the inner end of each of the Windlasses P. The fulcrum end is slotted, as seen at S in Fig. 2, and embraces the ratchet-wheel "I, which ratchet-wheel is placed upon and secured to thewindlass I. A pawl, U, is attached to the lever R near the ratchet-wheel, and takes hold of and falls into the angular teeth in the wheel, so that when thc lever R is caused to pass from V to W the Windlass Pis rotated upon its aXis, and the rope or chain M Wound up upon the Windlass I?, and when both levers are worked in concert the bottom K is elevated With great power till it reaches the height of the sheaves O. A pawl, U', attached to the side of the press above the ratchet- Wheels, serves to keep the Windlass from turning backward Whilethe lever R is being raised from W' to V in taking a new hold upon the Wheel T.

The mode ol' using this press is as follows:` The bottom K is placed at the lowest part of the frame, as in Fig. 3. The top is then raised and the interior of the press iilled with hay or other material to be pressed, and the top again closed and secured by means ofthe pins inthe hooks I, the door I3 being closed, as seen in Fig. l. Then the Windlass is turned by means of thev crank Q until the further condens-ation of the material to be pressed becomes difficult by this means. I then apply the power of the levers R until the required amount of density is produced. The bindingcords are now introduced through the slits C C C, and secured around the bale, When the top can be raised, the door opened, and the bale removed.

YVhat I claim as my improvement, and desire to secure by Letters Patent, is-

The special arrangement of the chain or rope M, pulleys L L', sheave O, and Windlass I?, in combination With the lever R, pawl and ratchet-Wheel U T, and bottom K,when these parts are arranged and operated as and for the purpose specified.
